Feb 15, 2023

The c.377A>G (p.K126R) alteration is located in exon 6 (coding exon 3) of the FAM149A gene. This alteration results from a A to G substitution at nucleotide position 377, causing the lysine (K) at amino acid position 126 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
